| Abstract | In this paper, a novel lithium-ion (Li-ion) battery charger is proposed; the proposed charger first takes the state of charge (SOC) information into account and adjusts the charging current accordingly. In order to further improve the charging efficiency, a fuzzy-logic-control-based (FLC-based) technique is also employed. The proposed FLC takes the temperature rise and the gradient of temperature rise of battery into account, and fine-tune the charging current accordingly. In this paper, the power stage is implemented using the synchronous-rectified buck converter. The digital compensator, digital filter and the SOC adaptive algorithm is implemented using the dsPIC digital signal controller from Microchip Corp; while the fuzzy logic controller is realized using the LabVIEW on a personal computer. In addition to the hardware, a graphical user interface is also presented. According to the experimental results, the charging efficiency of the proposed system can be increased and the performance of the proposed charger can be improved. Comparing to conventional constant-current constant-voltage (CC-CV) method, the proposed charging technique can reduce the average temperature rise for 23.2% while maintaining similar charging time. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
